Subject: [CRYPTO] hmac: Fix hmac_init update call
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5f77043f0f7851aa6139fb9a8b297497b540b397;p=openwrt%2Fstaging%2Fblogic.git

[CRYPTO] hmac: Fix hmac_init update call

The crypto_hash_update call in hmac_init gave the number 1
instead of the length of the sg list in bytes.  This is a
missed conversion from the digest => hash change.

As tcrypt only tests crypto_hash_digest it didn't catch this.
